Comparative Study Of Mecinus Janthiniformis (Coleoptera: Curculionidae) Attack And Simulated Mowing For Control Of Linaria Dalmatica Spp. Dalmatica (Plantaginaceae), Elizabeth J. Goulet, Antonio Ditommaso, Elson J. Shields

The Great Lakes Entomologist

Dalmatian toadflax, Linaria dalmatica spp. dalmatica (L.) Mill. (Plantaginaceae) has invaded over one million hectares in the western United States and Canada, in habitats similar to its native range. Two field studies were conducted to examine the impact of simulated mowing or insect herbivory on L. dalmatica growth and reproduction. Simulated mowing over the duration of the study decreased L. dalmatica total biomass per square meter, significantly reduced the total number of fruits and flowers per square meter, and resulted in significantly shorter flowering stems in the simulated mowing plots than in their controls. Plants in plots attacked by Mecinus …

Validation Of Ctmax Protocols Using Cased And Uncased Pycnopsyche Guttifer (Trichoptera: Limnephilidae) Larvae, David C. Houghton, Ashley C. Logan, Angelica J. Pytel

The Great Lakes Entomologist

The critical thermal maximum (CTmax) of a northern Lower Michigan population of Pycnopsyche guttifer was determined using four rates of temperature increase (0.10, 0.33, 0.50, and 0.70oC per minute), and two case states (intact and removed). Across all temperature increase rates, larvae removed from their cases had a significantly lower mean CTmax than those remaining in their cases, suggesting that the case can increase the larva’s ability to tolerate thermal stress, possibly due to respiratory advantages. Regardless of case state, mean CTmax was significantly lower at the 0.10oC per minute increase rate than the other three rates, likely due to …

Acizzia Jamatonica (Hemiptera: Psyllidae) And Bruchidius Terrenus (Coleoptera: Chrysomelidae: Bruchinae): Additional U.S. Records Of Asian Specialists On Mimosa (Albizia Julibrissin; Fabaceae), A. G. Wheeler, E. Richard Hoebeke

The Great Lakes Entomologist

Previously published U.S. records are reviewed for two recently detected Asian insects that have become established on mimosa, or silk tree (Albizia julibrissin), in the southeastern United States: Acizzia jamatonica (Kuwayama) (Hemiptera: Psyllidae) and Bruchidius terrenus (Sharp) (Coleoptera: Chrysomelidae: Bruchinae). The psyllid is newly recorded from Illinois, Indiana, Kentucky, Missouri, and Virginia and the bruchine chrysomelid from Illinois, Kentucky, Missouri, and Virginia. Both immigrant insects can be considered either detrimental or beneficial additions to the U.S. fauna, depending on whether mimosa is regarded as a desirable ornamental or an invasive plant. New and previously published records of both …

Supercooling Point Of Western Bean Cutworm (Lepidoptera: Noctuidae) Collected In Eastern Nebraska, Anthony A. Hanson, Silvana Paula-Moraes, Thomas E. Hunt, W. D. Hutchison

The Great Lakes Entomologist

Western bean cutworm, Striacosta albicosta (Smith) (Lepidoptera: Noctuidae), is a pest of maize and dry beans that has recently undergone a northeastern range expansion in North America. In order to assess the cold tolerance of S. albicosta, we determined the supercooling point of lab and field collected late instar larvae and pre-pupae. Individuals were attached to fine contact thermocouples and cooled at 1°C per minute to detect heat released due to freezing of body fluids. Mean supercooling points decreased as larvae developed into later life stages. Pre-pupa collected in late fall had a mean supercooling point of -12.63°C. This …

Insects Associated With Droppings Of Moose, Alces Alces (L), In Isle Royale National Park, Michigan, Alexander T. Egan, Roger D. Moon

The Diptera were Psychodidae, Anthomyiidae, Muscidae and representatives of three other families, and Coleoptera consisted of three species in each of Scarabaeidae, Staphylinidae and Histeridae. Species per sample ranged from two in early June to nine in mid-July, and a …

Geography And History Of Periodical Cicadas (Hemiptera: Cicadidae) In Dupage County, Illinois, Carl A. Strang

The Great Lakes Entomologist

The spatial distribution of periodical cicada (Magicicada septendecim L. and M. cassini Fisher) emergence in 2007 did not match either historical locations of woodlands or the cicadas’ own geography in the 19th and early 20th centuries in DuPage County, Illinois. Cicadas were present in forest areas that had remained above 61 ha throughout historic times, and they were absent from areas which at some point had been reduced below 52 ha by tree removal, mainly for agriculture. Isolation of forest areas also may have contributed to local extinctions. The insects have spread into new, urban woodlands created by residential …

Jutta Arctic (Oeneis Jutta) (Lepidoptera: Nymphalidae) Populations In Central And Northern Wisconsin: Localized Butterfly Populations In A Naturally Fragmented Landscape, Scott R. Swengel, Ann B. Swengel

The Great Lakes Entomologist

We recorded Oeneis jutta (Hübner) (Lepidoptera: Nymphalidae) at 60 of 78 peatland sites in central and northern Wisconsin on butterfly transect surveys on 113 dates during 2002–11. Additional observations come from informal observations on 19 dates in 12 years during 1987–2001. Most sites where we did not find O. jutta had little survey effort. The areas with the lowest O. jutta abundance (coastal and inland Bayfield County) had the shortest flight periods recorded in this study. O. jutta abundance negatively and significantly correlated with increasing wind speed and later times of day. O. jutta abundance significantly varied by bog vegetation …

The Effect Of Acclimation Temperature On The Critical Thermal Maximum Of A Cold-Water Population Of Pteronarcys Dorsata (Say) (Plecoptera: Pteronarcyidae), Logan Shoup, David C. Houghton

The Great Lakes Entomologist

The critical thermal maximum (CTmax) of Pteronarcys dorsata (Say) acclimated in the laboratory to 5 different temperatures ranging from 4 to 28°C was 34.7–36.6°C. A 6th temperature (33°C) resulted in 100% mortality during the acclimation period. Although its CTmax values rank P. dorsata as moderately sensitive to thermal stress, the < 2°C difference over a 7-fold increase in acclimation temperature suggests only a weak ability to adapt to warming conditions relative to other tested aquatic insect species. This stenothermy in P. dorsata was likely due to the consistently cool stream in which this populations lives. Our results suggest that cold-water populations are particularly susceptible to thermal alterations. They also provide the first CTmax values for a species of pteronarcyd stonefly and the first of any aquatic insect over such a …

Observations On Egg Parasitism Of Aeshna Tuberculifera (Odonata: Aeshnidae) By Eulophidae, Trichogrammatidae And Mymaridae (Hymenoptera) In Alger County, Michigan, Burton C. Cebulski, Mark F. O'Brien

The Great Lakes Entomologist

Egg parasitoids were reared from a population of Aeshna tuberculifera (Odonata: Aeshnidae) in the Kingston Lake area of Alger County, Michigan, from 1983-2005. Leaves of Iris versicolor were repeatedly used for oviposition during the period of observation, with the result that just a few leaves were targeted by different females. Seven species of parasitic Hymenoptera were reared from 1688 eggs. The cumulative rate of parasitization over the course of the study was 18.4%. Three species of parasitoids were responsible for approximately 96% of the parasitized eggs: Aprostocetus (Ootetrastichus) mymaridis Girault (Eulophidae) (41%); and the Mymaridae Polynema nr. needhami (34%) and …

A sample of 21 Gordionus violaceus (Baird) (Nematomorpha: Gordioidea) was obtained from a puddle in Winona County, southeastern Minnesota. These are the first of this species reported from the upper Midwest. Sex ratio was not significantly different from 50:50 and females and males did not differ significantly in length, but females were of significantly greater diameter than males.

Demonstration Of Sex Pheromones In Anabolia Bimaculata, Hydatophylax Argus, And Nemotaulius Hostilis (Trichoptera: Limnephilidae), David C. Houghton

The Great Lakes Entomologist

The presence of extractable semiochemicals for mate attraction is demonstrated experimentally for the first time in Anabolia bimaculata (Walker), Hydatophylax argus (Harris), and Nemotaulius hostilis (Hagen), three species of limnephilid caddisfly. Each species is also the first member of its respective genus to demonstrate pheromone presence. Sex pheromones appear to be wide- spread within the Trichoptera, although < 1% of species have been tested and there remains substantial research still to be done on pheromone demonstration, chemical composition, and release behavior.

Impact Of Mecinus Janthinus (Coleoptera: Curculionidae) On The Growth And Reproduction Of Linaria Dalmatica (Scrophulariaceae), Elizabeth J. Goulet, Jennifer Thaler, Antonio Ditommaso, Mark Schwarzländer, Elson J. Shields

The Great Lakes Entomologist

Dalmatian toadflax, Linaria dalmatica (L.) Mill. (Scrophulariaceae), a native to the eastern Mediterranean and Black Sea regions of Europe and Asia, has invaded over one million hectares in the western United States and Canada, in habitats similar to its native range. Once established, the aggressive vegetative growth of the plant allows it to invade undisturbed habitats where it can out-compete most other vegetation, placing native plant communities at risk.

Biological control of L. dalmatica with Mecinus janthinus Thomson (Coleoptera: Curculionidae) has shown promise in the field. In both studies reported in this paper, the presence of insect attack reduced L. …

Diversity And Community Structure Of Stream Insects In A Minimally Disturbed Forested Watershed In Southern Illinois, J. E. Mcpherson, Jacqueline M. Turner, Matt R. Whiles

The Great Lakes Entomologist

The Lusk Creek Watershed, located in Pope County, IL, long has been rec- ognized as a high quality area of biological significance, but surveys of the stream macroinvertebrate fauna have been limited. Thus, a survey of the benthic insect community at 11 sites in the upper portion of Lusk Creek was conducted from May 2003 to April 2005. A total of 20,888 specimens, mostly immatures, were examined during the study and represented eight orders. The Diptera, by far, was the most abundant order, with 18,590 specimens, almost all of which were members of the Chironomidae or Simuliidae. Members of the …

Discontinuity In The Insect Assemblages Of A Northern Lower Michigan Stream, David C. Houghton, Constance M. Brandin, Leila Reynolds, Lindsey L. Elzinga

The Great Lakes Entomologist

We assessed the physicochemical and biological continuity of a 2nd–4th order reach of the Little Manistee River in northern Lower Michigan. Contrary to typical woodland streams, the downstream sites of the river were covered with a dense riparian canopy, whereas the upstream sites were devoid of this canopy due to historical (≥10 ybp) agriculture. Other than slight changes in water temperature and dissolved oxygen, there were no appreciable differences in measured water physicochemistry between the canopied and non-canopied sites. The stream, however, appeared biologically discontinuous as indicated by lower shredder abundance and higher filtering collector abundance at the upstream (non-canopied) …

Attraction Of Agrilus Planipennis (Coleoptera: Buprestidae) And Other Buprestids To Sticky Traps Of Various Colors And Shapes, Toby A. Haack, Robert A. Haack, Therese M. Poland

The Great Lakes Entomologist

The family Buprestidae (Coleoptera) contains numerous economically significant species, including the emerald ash borer (EAB), Agrilus planipennis Fairmaire, first discovered in North America in 2002. Effective traps for monitoring spread and population densities of EAB and other buprestids are needed. Studies were conducted in 2008 to test different colors and shapes of sticky traps baited with manuka oil for capturing EAB and other buprestids. Among different trap shapes, an enlarged purple Agrilus-shaped silhouette (15 cm wide × 55 cm all) attached to a white background (40 cm wide × 60 cm tall) captured the most buprestid species compared to …

Variation In Lepidopteran Occurrence In Hemlock-Dominated And Deciduous-Dominated Forests Of Central Appalachia, L. E. Dodd, Z. Cornett, A. Smith, L. K. Rieske

The Great Lakes Entomologist

Eastern hemlock, (Tsuga canadensis Carrière, Pinaceae), is threatened with extirpation by an exotic invasive herbivore, the hemlock woolly adelgid, (Adelges tsugae Annand, Homoptera: Adelgidae). Given this threat, a broader and more detailed knowledge of the community associated with eastern hem- lock is merited. As Lepidoptera are important members of forest communities, this study was initiated to determine the relative occurrence of Lepidoptera in hemlock-dominated and deciduous-dominated habitats by evaluating abundance, species richness, temporal variation, and composition overlap. Lepidoptera were surveyed using blacklight traps from May – August 2010 at two collection sites in the Appalachian region of eastern …
